Sandra Bullock's 'On-Screen' Adopted Son Says She Will Make 'An Exceptional Mother!'

Sandra Bullock’s Blind Side co-star Quinton Arnold has seen Sandy’s maternal instincts in action and he knows she will be a great mom.

Before she was a mom to baby Louis, Sandra Bullock played an adopted mother in The Blind Side. Her onscreen son Quinton Arnold couldn’t be happier for his co-star now that she has adopted a baby in real life.

“I am truly overjoyed for Sandra – what amazing news and so special that she has been able to keep this time private between her and the baby!” Arnold told People magazine. ” Just as she played an exceptional mother in The Blind Side, her caring nature will make her an amazing mother to Louis!”

Sandra, 45, adopted Louis Bardo Bullock, now 3 and a half months old with her husband Jesse James, 41, in January. People magazine revealed yesterday that they “began the adoption process four years ago and brought Louis home in January, but decided to keep the news to themselves until after the Oscars. Their close friends and family – including James’s children Sunny, 6, Jesse Jr., 12, and Chandler, 15 – were essential in keeping the adoption a secret.” Sandra filed for divorce from Jesse last week in Texas. “I’m sad and I am scared,”she said.

But being a new mama seems to suit the Academy Award winner, who also told the magazine she is running on mommy adrenaline:

“I really only need three hours of sleep. I have learned that a little person screaming at the top of his lungs can mean six things: ‘I am hungry, I am wet, I am tired, I am uncomfortable, I am in pain, or I have gas.’ And I will figure out which one it is and fix it.”
